Process for recovering carbon and / or basalt material and carbon and / or basalt fiber web

摘要

The present invention relates to processes for recovering carbon and / or basalt material from at least one carbon and / or basalt fibers and / or filaments and textile fibers and / or textile fabrics and / or textile waste and / or filaments containing foreign fibers and / or filaments remnant. The object of the present invention is to provide a method for recovering carbon and / or basalt material for its reuse, which can be implemented with little expenditure of energy and time and can be easily integrated into a textile-technological processing sequence and in which the carbon fiber and / or basalt material of high purity can be recovered. In addition, to be provided by recycled carbon and / or basalt material by the present invention, a favorable for textile technology processing starting material. This object is achieved by a method of the abovementioned type, in which the at least one textile mixture and / or textile fabric and / or textile waste or remaining piece is mechanically dissolved, the dissolved material is carded and deposited in a fiber blended pile, and the fiber blended pile is irradiated with at least one laser. The object is further achieved by carbon and basalt fiber pile, which is produced with an embodiment of the method according to the invention.
